Question
The pressure P and volume V of an ideal gas both decreases in a process.
Options
A.The work done by the gas is negative
B.The work done by the gas is positive
C.The temperature of the gas must decrease
D.Heat supplied to the gas is equal to the change in internal energy.
Solution
W = PdV. then W = −ve
As pressure and volume both decreases
∴ temperature of system decreases
As pressure and volume both decreases
∴ temperature of system decreases
